This is a Plus icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,000 icons, all in the same style and quality.

Story about Plus Icon

I get it, my world view might be a little negative. What can I say, I call 'em like I see 'em, and the world ain’t a perfect place. Sure, most of my buddies think I’m a grouch, but I see myself as more of a realist. I don’t get caught up in all that nonsense—like there’s something wrong with you if you don’t have a smile plastered to your face 93 hours a day. Cynical as I may be, at least I keep it to myself unless I’m asked.

Not everyone has that kind of respect.

Take this free Plus icon download, for example. This guys walking around like he’s got something to prove. Always smiling like he just ate a sandwich made of million dollar bills. I get it, Plus icon might have things a little better than me, but that don’t make me grouchy. Good for him. So what if he doesn’t have to shower in second hand water and eat banana skins for dinner. We all can’t be as lucky as Plus icon. That’s fine, more power to him. But could he just stop rubbing that damn positivity in my face all the time? To be honest, it just feels like a show. Come on back to Earth with the rest of us and eat your crap sandwich.Some people just gotta tell everything to everyone—bragging every which way when they got it good, and sobbing to the whole world when things aren’t looking so hot.
